Display Solid rectangle and square star pattern in Java
In this article, we will discuss the concept of Program to Display solid rectangle or square star pattern in the Java programming language
In this post, we are going to learn how to write a program to print solid rectangle or square star pattern in Java using for loop, while loop and Do-while loop with example programs
Program 1
Display solid rectangle or square star pattern
Print solid rectangle using for loop
This program allows the user to enter the number of rows and columns and then it will display the solid rectangle or square pattern using for loop in Java programming language
import java.util.Scanner; class RectanglePat1{ public static void main(String args[]){ int rows,columns;//declare variable size Scanner scan=new Scanner(System.in); //create a scanner object for input System.out.print("Enter the nunber of rows: "); rows=scan.nextInt(); //get input from the user for row System.out.print("Enter the nunber of rows: "); columns=scan.nextInt(); //get input from the user for coloum for (int i=1; i<=rows; i++){ for (int j=1; j<=columns; j++){ System.out.print("*"); } System.out.print("\n"); } } }
When the above code is executed, it produces the following results
Program 2
Print solid rectangle using while loop
This program allows the user to enter the number of rows and columns and then it will display the solid rectangle or square pattern using while loop in Java programming language
import java.util.Scanner; class RectanglePat2{ public static void main(String args[]){ int rows,columns;//declare variable size Scanner scan=new Scanner(System.in); //create a scanner object for input System.out.print("Enter the nunber of rows: "); rows=scan.nextInt(); //get input from the user for row System.out.print("Enter the nunber of rows: "); columns=scan.nextInt(); //get input from the user for coloum int i=1; while( i<=rows){ int j=1; while(j<=columns){ System.out.print("*"); j++; } System.out.print("\n"); i++; } } }
When the above code is executed, it produces the following results
Program 3
Using the do-while loop
This program allows the user to enter the number of rows and columns and then it will display the solid rectangle and square pattern using the do-while loop in Java programming language
import java.util.Scanner; class RectanglePat3{ public static void main(String args[]){ int rows,columns;//declare variable size Scanner scan=new Scanner(System.in); //create a scanner object for input System.out.print("Enter the nunber of rows: "); rows=scan.nextInt(); //get input from the user for row System.out.print("Enter the nunber of rows: "); columns=scan.nextInt(); //get input from the user for coloum int i=1; do{ int j=1; do{ System.out.print("*"); j++; }while(j<=columns); System.out.print("\n"); i++; }while( i<=rows); } }
When the above code is executed, it produces the following results
